Looking for 1GG7-4210 amplifier datasheet

 

Hello,

I am looking for the HP 1GG7-4210 MMIC amplifier datasheet or at least the +VD and -VG values for this amplifier

Best regards

The IC looks like an old HP traveling wave amplifier, but what¡¯s around it does not look like it was made at HP. The gate voltage (bottom left pin with the wire going to the feedthrough) is quite likely adjusted to give a certain drain current, so it won¡¯t be a fixed number on the data sheet. Vd is probably 5-7V. Sorry, I don't have the data sheet.

Just a guess, in case you can't find the data sheet:

Vd=7V
Id is adjusted for 150mA max. or leave it at Idss if it's less than 150 mA.

Could this be an Avantek part after spinning out from HP?
 

No, not Avantek. The IC (just the chip) is supposedly still in production at Keysight, but I have no idea if it's still available in that package. I think it was designed in the 1980s.

Hello,
?
I was finally able to do some first tests on this MMIC
?
The tests have been performed on a WESSEX Electronics amplifier 6003-03-009 ( 3 stages with three 1GG7-4210 )
?
The results are :
?
Vd = 5 to 8V? Current : around 600mA? with Vg = -0.05V
?
BW for "flat" gain from 1 ( may be below ) to 15.5 Ghz
?
@ 10.368 Ghz
Pin = 0dBm - Pout = +17dBm @Vd = 5V
Pin = 0dBm - Pout = +17.5dBm @Vd = 7V
Pin = 0 dBm - Pout = +18 dBm @ Vd = 8V
?
@ 5.760 Ghz
Pin = 0dBm - Pout = +18dBm @Vd = 5V
Pin = 0dBm - Pout = +18.5dBm @Vd = 7V
Pin = 0 dBm - Pout = +19 dBm @ Vd = 8V
?
So a quite large BW but low gain...
?
Best 73s
